Launch Window

The next few rocket launches from the site you care about, with a live countdown to the one at the top.

Pick a launch site and see the next few launches with a countdown that tracks the real window. Working name only; the real one is still in the oven.

The countdown tracks the window, not a guess — when a launch slips, the number on your screen slips with it.

Step 3
Watch the clock

A live countdown to the top launch, on the home screen and in a widget. It follows the window when the window moves.

Built for people who look up

I live in Florida. Half the launches I've seen, I saw by accident — someone texted me 40 seconds before the roll. The rest I missed completely: the first I hear of most launches is the rocket itself, and by then it's too late to look up. This is the app that texts you first.

A nudge, not a firehose

Three heads-ups — T-2 hours, T-30 minutes, T-5 minutes — plus one if it holds and one if it scrubs. Not every schedule change.

Works on a bad connection

The last known schedule stays on the device, so the countdown keeps running.

Visibility, not just timing

Whether it's a daylight launch, so you know if there's actually something to see.

No account

Open it and it works. Nothing to sign up for, nothing to log in to.

What it doesn't do
  • No account required. Nothing to sign up for.
  • No ads, no analytics resold to anyone.
  • It won't promise a launch will happen. Weather wins.

Launch times come from public launch schedules and can change without notice.
